方向性效应 meaning in English

beam-shaping effect

The result obtained in this study shows that : the source time functions retrieved from p - and s - waves recorded at different stations distributed at different azimuths show prominent directivity
结果表明：从不同方位台站的z分向p波和sh波提取的震源时间函数显示了明显的方向性效应。
The directivity shows that the np i is the fault plane , and that the earthquake ruptured unilaterally from the northeast to the southwest , nearly perpendicular to the strike of the java trench
P波显示的方向性效应表明：走向为199的节面是断层面。破裂传播方向为自东北向西南方向，几乎垂直于爪哇海沟走向。
The source time function directivity is in accordance with the p waveform directivity , clearly showing that the nodal plane of strike 199 is the fault plane and that the earthquake ruptured unilaterally from the northeast to the southwest
震源时间函数的这种方向性效应与p波的方向性效应相一致，清楚地表明：走向为199的节面为断层面，地震是从东北向西南方向单侧破裂的。
